Week 3

(1/23/12-1/27/12) 

1. Overview of Status of Analysis, Design, Fabrication, Test, etc

   1. • Redesigned the platform to minimize the inertia, torque, and power specifications

        • Discussed fabrication process with Tom and Isaiah

      • Determined the optimal materials that can withstand the functional requirements

        • Temperature range

        • Fatigue 

        • Creep

        • Stress

      • Determined motor, controller, and encoder combination that meet the new specifications

2. Goals for next week

• • Speak with our sponsor, Dr. Babcock, about our design

    • Confirm our design and analysis that has been performed

3. Instructor comments from last meeting and actions taken

• • Kinematics analysis

    • Conducted motor simulations for geared motors

    • Conducted motor simulations for direct drive motors

    • Decided on direct drive motors for optimized performance

4. Risks and areas of concern

• • Mounting of the motor

    • We need to analyze the position of the motors to minimize the inertia

  • Price of the motor

    • Even though direct drive motors are the best solution, they are more expensive

  • Find out which driver is the best solution

    • AKD drivers have been our choice; however, they can only handle 1 axis

      • Buying 2 same drivers might not be the best option

    • Look for a cheaper and programmable driver and controller

5. Schedule

• • Contact suppliers

    • Find out the lead time of the motors and the drivers

    • Find out the price of the motors and the drivers

6. Budget

• • Risk Reduction: $215.20 

  • Remaining: $3284.80

7. Progress

• • Working on weekly report and CAD pages

  • Will be uploading CAD files as soon as all the parts are made

  • Presentations are uploaded
